According to barriers for the use of electronics in the progress path and with regard to the appearance
of new technologies, such as light and quantum, and their numerous benefits, combined light and quantum
should be used to enjoy all these advantages. There is no doubt that the changes must also be done in making
circuits using base gates based on new design of both the light and quantum technology. Thus, in this study,
we propose quantum fault-tolerant reversible MIG gate using the optical components for the first time. Then,
by using it, we propose an optical quantum fault-tolerant reversible full adder. Obviously, the design can be
applied in the optical computing, quantum computing, DNA computing, as well as genetics and
nanotechnologies, considering the increased fault tolerance. All the scales are at the nanometric level.
